A correction to the Migrating RAID article in issue 168 (November 2014).
The last paragraph on page 40 of issue 168 (November 2014) mentions iosetup twice. The actual command is losetup as follows:
Nothing can now prevent a successful boot with the virtualized system. If you have disks that were mirrored on hardware controllers – and provided the mirror was in a synchronized state – you only need to restore one disk. You can convert it to .dd format with Xmount. Sigfind provides the offset to the translated MBR, and you can then run losetup,
losetup -o $(((1024+2048)*512)) /dev/loop0 image.dd
to create a loopback device with an MBR offset of 1024, and the beginning of the first partition at sector 2048, where you can then mount it.
